Analysts said the end of the Murdochs' marriage was unlikely to have an impact on the media empire.

Murdoch and Deng had a prenuptial agreement, according to a person familiar with the situation. Their girls have stakes in the family trust that holds the Murdochs' stake in News Corp, but they do not have voting rights.

"I doubt it has a substantial impact on the spin," Gabelli & Co analyst Brett Harriss said, referring to the News Corp separation. "Given that it's his third wife, I see it unlikely that he didn't plan for this contingency."
